Chapter 6 Group resource details
496
In ExpressCluster, accesses to a shared disk are controlled by HBA (Host Bus Adapter)
settings. Configure HBAs that connect a shared disk to control accesses. For details, refer to
“HBA tab” in Chapter 3, “Function of the Builder.”
� Configuring DISK network partition solution resource
When a disk resource is used, it is recommended to use DISK network partition solution
resource. For details on DISK network partition solution resources, refer to “Understanding
network partition resolution by DISK method” in Chapter 9, “Details on network partition
resolution resources.”
Notes on disk resources
Note 1 Make settings so that the same partition is accessible with the same drive letter on all
servers.
Note 2 If a drive letter different from the one used on partition is set, the drive letter will be
changed when the disk resource is started up. If the drive letter is used on other
partitions, starting up the disk resource will fail.
Note 3 Dynamic disk is not supported. If a partition on dynamic disk is used for disk resource,
starting up the disk resource will fail.
Note 4 Configure HBAs for a partition used for disk resource. If a partition without HBA
configuration is used for disk resource, starting up resource will fail.
When HBA configuration is changed, OS reboot is required to reflect the changes. If
OS is not rebooted after changing HBA configuration, starting up disk resource will
fail.
For details on HBA configuration, refer to “HBA tab” in Chapter 3, “Function of the
Builder.”
